SPECIFICATION forming part of Letters Patent N 0. 582,282, dated May 11, 1897. Application filed November 20, 1896. Serial No. 612,862. (No model.)

To all whom it may concern.-

Beit known that I, J OHN B. GREINER, a citizen of the United States, residing at Jacksonville, in the county of Duvaland State of Florida, have invented certain new and useful Improvements in Motors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has reference to a novel construction in a wave-motor-that is to say, a novel construction for utilizing or storing up the energy due to the undulations of a body of water.

The invention consists in the features of construction hereinafter fully described and specifically claimed.

In the accompanying drawings, forming a part of this specification, Figure l is a central vertical section of a wave-motor constructed in accordance with this invention; and Fig. 2 is atop plan of the same, illustrating only one of the devices whereby the wave energy is utilized. Fig. 3 is a side elevation of the same. Fig. 4 is a central vertical section of the compression apparatus on an enlarged scale. Fig. 5 is a cross-section of one of the valves, and Fig. 6 is a top plan of the same.

In accordance with the principle involved I by this invention it is intended to employ the energy of the undulations or waves of a body of water that is usually wasted, and the accompanying drawings illustrate an approved form of apparatus to be used for this purpose, although it is obvious that various changes can be made in the construction and details thereof without departing from the spirit of this invention as hereinafter claimed, and therefore, except in the claims for the specific construction, I do not wish to be limited to the exact details hereinafter shown and described.

In said drawings, 1 indicates a platform which supports the operative parts of the motor. This platform is situated in the body of water and is preferably fastened in a stationary manner. In the accompanying drawings this platform is shown circular in plan, as it is found to be the most economical construction that can be employed in a motor of said reservoir are a plurality of compressors or pumps 5 (shown in details in Fig. 4) and which communicate with said reservoir by means of the valved passages 6, leading from the lower ends thereof. The upper ends of these compression-chambers 5 are provided with heads 7, having an opening for the piston-rod 8, and provided also with a'valved inlet-opening 9 for the fluid to be compressed. The pistons 10 are situated within said chambers 5 and are provided with valved openings 11, establishing communication between the upper and lower ends of the chamber. The valves of the passages 6 and openings 9 and 11 open inwardlythat is to say, they open toward the reservoir 2.

In accordance with the broad principle involved by this invention the piston-rods 8 of the compressors or pumps are connected with suitable devices that are reciprocated by the undulations of the water, whereby these pistons are moved back and forth to force the fluid into the reservoir 2, and in the accompanying drawings the construction whereby these pistons are moved consists of floats 15, situated around the platform 1 and held by suitable guides 16, consisting of upright posts or spiles rigid with relation to the platform. The said floats 15 are preferably rectangular in cross-section and are provided with the guide-rollers 17, that run upon the guides or spiles 16, and thus reduce the friction between the said floats and guides. Mounted upon the top of the platform 1 and adjacent to the compressor is an upright 18, to which is pivoted a lever 19, connected at its inner end with the piston 8 and at its outer end with the floats 15. The connection between said lever 10 and the floats conveniently consists of a yoke ,or loop 20, conveniently situated upon the top of the float that receives the end of the lever 19. It can be seen from the foregoing description that in a platform which is circular in plan these levers and movable floats are radially arranged, as shown in Fig. 2; and to allow the requisite reciprocation of the lovers and floats the outer portions of the platform are slotted, as shown at 21, to allow the outer end of the levers 19 to fully descend. The valves controlling the passages 6 and the openings 9 and 11 are all constructed in the following manner: The heads and piston of the compressor are each provided with a screw-threaded opening a to receive the valvecasing b. This valve-casing b has a central chamber 0, that is closed at its upper end by a plug d, having an inwardly-projecting stop 6. An inlet-passage f leads from the upper end of the casing through the side thereof to the center of the lower end of the chamber a, while an outlet-passage 9 leads from the upper end of the chamber 0 through the side of the casing to the lower end thereof. A valve it, having guide-arms i, is situated within the chamber and is adapted to rest upon a washer 7.; at the lower end thereof. The stop e limits the upward movement of said valve, which reaches to the lower side of the upper end of the outlet-passage. It is thus seen that when the pressure on opposite sides of the valve is equal said valve closes by gravity, but opens when the pressure on the side communicating with the inlet-passage decreases.

It will be apparent from the foregoing description that owing to the undulations of the water these floats will rise and fall, and by means of the connections described will raise and lower the pistons and force the fluid, which maybe air, for instance, into the reservoir 2, where it can be stored under compression or may be used as it accumulates, as most convenient. The manner in which the fluid is employed after being stored or forced into the reservoir does not form a part of this invention and can be carried out in any manner desired. A motor of this kind is not only simple and automatic in its action, but is economical owing to the fact that the energy utilized is attained without expense more than the motor itself and the connections for obtaining the fluid compressed thereby.

Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, is-- 1. A motor of the kind specified consisting of a platform having a reservoir situated at about the center thereof, a plurality of compressors or pumps carried by said platform and situated around said reservoir and com municating therewith with valved pipes or passages, upright guides at the sides of said platform opposite each of said compressors or pumps, slots in the outer portion of the platform, buoyant members provided with rollers and situated within said guides, and levers connected with said compressors or pumps, pivoted upon the platform, and having a sliding connection with said buoyant members.

2. A valve consisting of a central chamber having an inlet -passage leading from the lower end thereof to a point above the chamber, an outlet-opening leading from the upper end thereof to a point below the chamber, and a valve situated in said chamber.

3. A valve consisting of a central chamber having an inlet-passage leading from the lower end thereof to a point above the chamber, an outlet-passage leading from the upper end thereof to a point below the chamber, a stop in the upper end of said chamber, and a valve situated within said chamber.

4. The combination of a valve-casing having a central chamber provided with a stop at its upper end, an inlet leading from the lower end of said chamber to the side of said casing and communicating with an upright passage cut in the side of said casing, an outlet leading from the upper end of said chamber to the side of said casing and com municating with a downwardly-extending passage cut in the side of said casing, of a valve situated within said chamber.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
